About This Project
RER Electrical & Solar Ltd. carried out a comprehensive energy audit at Dowd Engineering, assessing operational energy use and identifying opportunities for long-term efficiency improvements. Based on the audit, we designed and installed a custom 30kW Solar PV system with a 10kW three-phase inverter and 10kW battery storage to maximise renewable energy generation. Project Highlights:
We also managed all ESB documentation on behalf of the client, ensuring a seamless approval process.
The system is expected to produce approximately 33,000 kWh per year.
Significantly reducing grid electricity consumption and helping Dowd Engineering lower both energy costs and their carbon footprint.
This project provides Dowd Engineering with substantial long-term savings, improved energy efficiency, and a reduced environmental impact through the adoption of renewable energy.
